Crown Thin

Crown thinning is the removal of a small portion of secondary and small live branches

This techique produces a uniform density of foliage around an evenly spaced branch structure. It is usually confined to broad-leaved species.

Crown thinning includes the removal of dead wood and does not alter the overall size or shape of the tree. Common reasons for crown thinning are to allow more light to pass through the tree, reduce wind resistance or to lessen the weight of heavy branches and improve form.
